TOP.

SPECIF IGATION forming part of Letters Patent No. 229,531, dated July 6, 1880. Application filed May 27, 1880. (No model.)

To all whom it may concern Be it known that I, ROLAND GILLESPIE, a subject of the Queen of Great Britain now residing in Boston, in the county of Suffolk and Commonwealth of Massachusetts, have invented an Improvementin Gan-Tops, of which the following is a specification.

This invention relates to the following-described improvement in can-tops, reference being had to the accompanying drawings, forming a part of this specification, in explaining the nature of my invention, in which- Figure 1 is an elevation of the can-top. Fig. 2 is a plan thereof. Fig. 3 is a vertical section. Fig. 4 is a plan with the cap removed.

Gan-tops for kerosene and other cans have been made of sheet metal struck up and having the cap attached to the neck by a wire loop or staple. This method of securing a cap to the neck is a great improvement over the old form in that it is impossible that the cap be lost; but there are some defects in the construction which are obviated by my improvement-namely, the cap is very liable to be displaced by jars, and the contents of the can escape. By my invention the cap, while it is fastened to the neck, yet may be screwed into place, and therefore cannot readily be displaced.

A represents the neck. It is struck up or otherwise formed from sheet metal, and is provided with a screw-thread, a.

B represents the cap, and it is provided with a screw-thread, b, and is fastened to the neck by the wire loop or hook O. This loop or hook preferably is open at one end, and the cap is made with the upwardly-curved flange b, which is provided with the slots b, as shown, and the end of the wire is bent downwardly between the upper edge of the flange and the side of the cap.

In use the cap, having been secured to the neck, is screwed as in the ordinary screw-caps. After unscrewing, the cap cannot be removed from the neck, as the flange prevents it from being lifted from the wire loop.

In order to turn the cap over to expose the opening through the neck, it is necessary, after unscrewing the cap only, to turn the same until a slot is reached, when the cap can be turned over without being removed from the wire loop.

f The advantages of this invention are maniest.

In lieu of the flange b, struck up with the cap, a ring surrounding the cap and bearing substantially the same relation to the cap that the flange bears may be used and attached to the cap at one or more points.

Of course this invention may be used for can-nozzles as well as for can-tops.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States The improved can-top consisting of the neck A, provided with screw-thread, the cap B, adapted to screw thereon and having a slotted flange, and the wire hook or loop 0 for fastening the cap to the neck, substantially as and for the purposes described.

ROLAND GILLESPIE.
